For the longest time, or as far as I can remember, the holy grail of all networking platforms has been the need for a single pane of glass, that single source of all information that you would need to be most effective.
So, what is a single pane of glass?
If you take it at face value, it simply means a window that consists of a single square frame through which you can peek and get a panoramic view of what you are looking at. I don’t know how this term came to be, but it may be referring to the ability to look at a computer screen and get a snapshot view of everything such that you will not need to look elsewhere. Simpler said than done. The single pane of glass is not a myth, rather, it is an unobtainable objective whose value may have been over-hyped in order to differentiate from the rest. It is no different in Cybersecurity.
